When a Dutch child grows up during Nazi occupation watching his father return from a work camp, watching hunger hollow out his neighbors, watching liberation armies arrive too late for too many, trauma stops being an abstract concept. It becomes the air you breathe, the silence at dinner tables, the unspoken weight carried in bodies that survived what minds could not process. Bessel van der Kolk, born in The Hague in July 1943 amid bombing raids and mass incarcerations, spent his entire professional life trying to understand what he witnessed in those early years. His insight, articulated across five decades of clinical work and research, transformed how we understand psychological trauma. The body keeps the score, he wrote in his landmark 2014 book, and in those four words he captured what depth psychology had sensed for a century. Trauma lives in muscles and viscera, in breathing patterns and startle reflexes, in the ways bodies remember what minds have tried to forget.

Van der Kolk’s childhood in postwar Netherlands provided an unwitting education in collective trauma. His father had been imprisoned in a Nazi labor camp, his mother he describes as cold and unhappy, the household marked by his father’s rage and his own experiences of abuse. He learned six languages, played piano and cello, sought refuge in monasteries as a teenager, and eventually fled Europe for the United States. He completed his pre-medical studies with a political science major at the University of Hawaii in 1965, was active in Students for a Democratic Society, and was influenced by R.D. Laing and the anti-psychiatry movement that questioned whether mental illness was disease or reasonable response to unreasonable circumstances. This early exposure to radical critique would shape his later work, his willingness to challenge psychiatric orthodoxy about how trauma should be treated.

He received his medical degree from the Pritzker School of Medicine at the University of Chicago in 1970, completed his psychiatric residency at the Massachusetts Mental Health Center affiliated with Harvard Medical School in 1974, and began working as director of Boston State Hospital. His interest in traumatic stress crystallized in 1978 when he became a staff psychiatrist at the Boston Veterans Administration Outpatient Clinic, working with Vietnam veterans whose symptoms defied existing psychiatric categories. These men suffered nightmares, flashbacks, and numbing that came and went unpredictably, their bodies responding to threats that existed only in memory. Standard talk therapy offered little relief. The prevailing psychoanalytic approaches assumed that symptoms arose from unconscious conflict that could be resolved through interpretation, but these veterans were not neurotic in the classical sense. They were haunted by experiences that had overwhelmed their capacity to integrate what happened.

In 1982, while working as a junior faculty member at Harvard Medical School, van der Kolk founded the Trauma Center in Brookline, Massachusetts, one of the first clinical research centers in the United States dedicated to civilian trauma populations. This institutional base allowed him to conduct systematic investigations that would eventually span neurobiology, attachment theory, memory research, and treatment outcome studies. He pursued multiple research tracks simultaneously, demonstrating unusual intellectual range. He conducted the first studies on selective serotonin reuptake inhibitors for post-traumatic stress disorder, finding that while medications like fluoxetine provided some symptom relief, they rarely produced the profound transformation that trauma survivors needed. He became a member of the first neuroimaging team to investigate how trauma alters brain processes, using emerging functional MRI technology to show that traumatic memories activate different neural networks than ordinary autobiographical memories.

His research linking borderline personality disorder and deliberate self-injury to childhood trauma and neglect challenged psychiatric nosology that treated personality disorders as characterological flaws rather than adaptations to overwhelming experience. This work, published throughout the late 1980s and 1990s, demonstrated that what psychiatry labeled as pathological personality actually represented complex trauma responses that formed when caregiving systems failed children repeatedly. The person who cuts herself to feel something, who swings between idealization and rage in relationships, who dissociates when stressed, has not developed a disordered personality but has adapted brilliantly to circumstances where emotional regulation required drastic measures.

Van der Kolk’s work on traumatic memory proved particularly influential and controversial. In collaboration with Onno van der Hart, he explored how Pierre Janet, the 19th-century French psychiatrist, had understood trauma as causing dissociation, a splitting of consciousness that prevented traumatic experience from being integrated into narrative memory. Van der Kolk proposed that traumatic memories are encoded differently than ordinary memories, stored as sensory fragments and emotional states rather than coherent narratives. When triggered, these memory fragments intrude into consciousness as flashbacks, nightmares, or body sensations that feel utterly present rather than safely past. This theory suggested that trauma survivors were not choosing to remain stuck in the past but were neurologically unable to place traumatic experience into historical context.

During the 1990s, van der Kolk became a prominent proponent of recovered memory therapy, serving as an expert witness in criminal cases involving allegations of childhood sexual abuse that had purportedly been repressed and later recovered in therapy. This involvement in what became known as the memory wars drew fierce criticism from researchers like Richard McNally, who argued that therapeutic techniques for recovering repressed memories were creating false memories rather than accessing accurate ones. McNally’s 2003 book Remembering Trauma provided a detailed critique of van der Kolk’s theoretical model, concluding it was a theory in search of a phenomenon. The controversy damaged van der Kolk’s reputation in some academic circles, and his laboratory at Massachusetts General Hospital was closed in the late 1990s. Van der Kolk attributes this to institutional fear of lawsuits after he testified for the prosecution in cases involving recovered memories.

The memory wars reveal important tensions in trauma treatment. Van der Kolk’s clinical experience showed him that some survivors have periods of amnesia for traumatic events that later return to consciousness, while memory researchers demonstrated that therapeutic suggestion can create vivid false memories that feel entirely real. Both observations can be true. The brain’s memory systems are neither perfect recording devices nor wholly unreliable. Trauma can indeed impair memory consolidation, creating gaps and fragmentation, while social suggestion can indeed create compelling pseudo-memories. The challenge for clinicians is distinguishing between these possibilities without either dismissing survivors’ experiences or assuming all recovered memories are accurate. Van der Kolk’s later work became more cautious about memory recovery techniques, focusing instead on helping clients work with whatever memories they have, whether complete, fragmentary, or absent.

Despite this controversy, van der Kolk’s broader research program continued advancing understanding of how trauma reshapes physiology. He emphasized that trauma is fundamentally a disorder of arousal and regulation, a recalibration of the nervous system to interpret the world as dangerous. Following Abram Kardiner, who in 1941 called traumatic stress a physioneurosis, van der Kolk studied treatments that stabilize physiological systems, increase executive functioning, and help traumatized individuals feel fully alert to the present rather than trapped in defensive states. This emphasis on bottom-up regulation rather than top-down cognitive processing distinguished his approach from mainstream cognitive behavioral therapy.

Van der Kolk received the first National Institutes of Health grants to study Eye Movement Desensitization and Reprocessing and yoga for post-traumatic stress disorder. His 2007 randomized clinical trial comparing EMDR, fluoxetine, and placebo found that both EMDR and medication produced significant symptom reduction, but EMDR showed superior long-term maintenance of gains. The neuroimaging component of this research revealed that successful EMDR treatment did not reduce limbic arousal but instead enhanced activity in the anterior cingulate gyrus and left frontal lobe, suggesting that healing involved strengthening the capacity to differentiate real from imagined threat rather than eliminating fear responses entirely. This finding has profound implications. Trauma treatment does not erase traumatic memory or eliminate the body’s capacity for alarm but helps the nervous system contextualize threat accurately.

His research on trauma-sensitive yoga, funded by the National Center for Complementary and Alternative Medicine, demonstrated that yoga practice significantly reduced PTSD symptoms in women with treatment-resistant trauma histories. The study showed that yoga worked not primarily through the beliefs or narratives that participants adopted but through direct effects on nervous system regulation, improving heart rate variability and shifting autonomic tone toward parasympathetic dominance. This provided empirical support for what somatic therapies had long claimed, that changing how the body responds changes how the person feels and thinks, not the reverse.

Van der Kolk’s investigations of neurofeedback explored whether directly training brain wave patterns could ameliorate trauma symptoms. His 2016 randomized controlled study found that neurofeedback targeting specific EEG patterns significantly reduced PTSD symptoms and improved executive functioning, with gains maintained at follow-up. The mechanism appeared to involve enhancing the brain’s capacity to regulate its own arousal states, strengthening prefrontal control over limbic reactivity. A subsequent 2020 study with children who experienced developmental trauma showed similar benefits, suggesting that neurofeedback could address the attentional and perceptual disruptions that trauma creates during crucial developmental periods.

Most recently, van der Kolk served as principal investigator for the Multidisciplinary Association for Psychedelic Studies Phase 3 trial evaluating MDMA-assisted psychotherapy for severe PTSD. Published in Nature Medicine in 2021, this landmark study found that MDMA combined with psychotherapy produced substantially greater symptom reduction than placebo plus psychotherapy, with 71 percent of participants no longer meeting PTSD criteria after treatment. The journal Science selected this work as one of the ten most significant scientific breakthroughs of 2021. Subsequent analysis published in 2023 showed that MDMA appears to work by temporarily dissolving the rigid defensive structures that keep traumatic memory isolated, allowing therapeutic reprocessing under conditions of enhanced safety and connection.

In 1999, van der Kolk initiated the creation of the National Child Traumatic Stress Network, a congressionally mandated program that now funds approximately 150 centers across the United States specializing in treating traumatized children and their families. This network has studied more than 20,000 traumatized children and adolescents, leading to van der Kolk’s proposal for Developmental Trauma Disorder, a diagnostic category meant to capture the complex constellation of symptoms that arise when children experience chronic interpersonal trauma during critical developmental periods. These children typically present with dysregulation across multiple domains including affect, attention, behavior, cognition, relationships, and physical health, but they often fail to meet criteria for PTSD because their trauma is not a discrete event but an ongoing environment.

The American Psychiatric Association has not accepted Developmental Trauma Disorder into the Diagnostic and Statistical Manual, partly due to concerns about overlap with existing diagnoses and partly due to resistance to expanding trauma-based diagnoses. This rejection reflects broader tensions in psychiatry about whether to emphasize categorical diagnoses or dimensional approaches to psychopathology. Van der Kolk has argued that failing to recognize how developmental trauma creates its own syndrome leaves clinicians without adequate frameworks for treatment planning and forces traumatized children into diagnostic categories that do not fit their actual presentations.

The Body Keeps the Score, published in 2014, became an unexpected cultural phenomenon, spending years on the New York Times bestseller list and being translated into 43 languages. The book synthesizes van der Kolk’s research and clinical experience into an accessible narrative that moves between neuroscience, case studies, and exploration of innovative treatments including EMDR, neurofeedback, yoga, theater, and Internal Family Systems therapy. His central argument runs throughout: trauma is not primarily a disorder of cognition or emotion but a disorder of the body, and healing requires engaging the body’s sensorimotor systems rather than relying solely on verbal processing.

The book’s success stems partly from how it validates experiences that trauma survivors recognize but that mainstream psychiatry often dismisses. When van der Kolk describes how traumatized people feel fundamentally unsafe in their bodies, how they may dissociate during sex or medical procedures, how they startle at sounds that others barely notice, how they feel simultaneously numb and hypervigilant, he is describing phenomena that trauma survivors know intimately but rarely see acknowledged in medical contexts. The book gave language to embodied experiences that had been pathologized or ignored.

However, the book has also drawn substantial criticism from researchers who argue it oversimplifies neuroscience, promotes treatments with limited evidence bases, and makes claims that distort or exaggerate research findings. A 2023 editorial in Research on Social Work Practice criticized van der Kolk for regularly ignoring or misrepresenting the scientific knowledge base of PTSD treatment. Skeptical Inquirer writer Peter Barglow accused him of endorsing controversial treatments including Emotional Freedom Technique, which involves tapping acupressure points while thinking about trauma, a practice that controlled studies have not shown to be more effective than placebo.

A 2024 Mother Jones article by journalist Emi Nietfeld offered a scathing critique, arguing that The Body Keeps the Score stigmatizes survivors, blames victims, and depoliticizes violence by locating trauma primarily in individual bodies rather than in social conditions that produce traumatic experiences. She contacted researchers whose work van der Kolk cites and reported that multiple scientists said the book distorted their findings. The evidence the book presents regarding how trauma is remembered by the body remains contested among memory researchers, and the claim that traumatic memories are stored differently than ordinary memories has been disputed by studies showing that traumatic and non-traumatic memories share similar encoding and retrieval processes.

These criticisms highlight real concerns about how trauma discourse can inadvertently pathologize normal responses to abnormal situations, locate healing primarily in therapeutic interventions rather than in social change, and present contested theories as established facts. Van der Kolk’s emphasis on the body keeping the score can suggest that trauma permanently damages people unless they receive specific treatments, potentially undermining survivors’ inherent resilience and capacity for meaning-making. His focus on individual nervous system regulation may deemphasize how trauma arises from systemic oppression, poverty, racism, and violence that therapy alone cannot address.

Yet these criticisms coexist with the reality that van der Kolk’s work has profoundly helped many trauma survivors and clinicians. The question is not whether his theories are flawless but whether they offer useful frameworks for understanding and alleviating suffering. From a depth psychology perspective, what matters is whether the ideas resonate with lived experience and open pathways for healing, not merely whether they conform to current empirical standards. Jung distinguished between truth and reality, suggesting that psychological truth involves what feels meaningful and generative even when empirical reality remains uncertain.

Van der Kolk’s emphasis on the body aligns remarkably with Jungian concepts about the psychoid nature of complexes. Jung insisted that psychological complexes are not merely mental but have somatic components, that emotional material embeds itself in tissues and continues to operate through visceral disturbances. When Jung spoke of the shadow, he meant not just disowned psychological content but material that manifests through bodily symptoms, through the way a person holds tension in their jaw or restricts their breathing. Van der Kolk’s focus on how trauma recalibrates the autonomic nervous system, creating patterns of hyperarousal or numbing that persist long after danger has passed, gives neurobiological specificity to Jung’s observation that unconscious material seeks expression through the body.

Active imagination, Jung’s technique for engaging unconscious material, involves attending carefully to bodily sensations, images, and movements that arise spontaneously when consciousness is relaxed. Practitioners are instructed to notice where in the body they feel particular emotions or images, to allow the body to move in ways it wants to move without conscious direction. This process works with what van der Kolk calls the subcortical, nonverbal processing systems that store traumatic memory as sensory and motor patterns. When someone in active imagination allows their body to tremble, or to adopt protective postures, or to complete interrupted defensive movements, they are accessing the somatic level where trauma is encoded.

The implications for clinical practice are substantial. Van der Kolk’s research validates approaches that Jung pioneered phenomenologically. Therapists working with trauma need to attend not just to what clients say but to how they breathe, how they move, where they hold tension, how their autonomic state shifts during session. Sensorimotor Psychotherapy, developed by Pat Ogden drawing explicitly on van der Kolk’s work, teaches therapists to track clients’ somatic experiences moment by moment, helping them complete defensive responses that were interrupted during trauma, building capacity to tolerate activation without dissociating or flooding.

Somatic Experiencing, Peter Levine’s approach, similarly emphasizes working with the body’s innate capacity to discharge arousal through trembling, shaking, and other autonomic releases. Levine observed that animals in the wild regularly experience life-threatening encounters but rarely develop chronic traumatic stress because they allow their nervous systems to complete the arousal cycle rather than suppressing natural discharge. Humans, with our capacity for inhibition and our cultural injunctions against losing control, often freeze these natural processes, leaving arousal trapped in the system.

For brainspotting and EMDR practitioners, van der Kolk’s neuroimaging research provides insight into mechanisms. When a client maintains dual awareness, holding traumatic material in mind while tracking eye movements or maintaining eye position that accesses subcortical processing, they are activating the very prefrontal regions that van der Kolk’s imaging studies showed become enhanced after successful treatment. The alternating bilateral stimulation appears to facilitate integration between hemispheres and between cortical and subcortical systems, allowing traumatic memory to be reconsolidated with updated information about safety.

The research on yoga and neurofeedback suggests that trauma treatment can work not only through processing specific memories but through building general regulatory capacity. Someone who practices yoga learns to notice subtle proprioceptive and interoceptive signals, to breathe consciously during activation, to distinguish between challenge and threat. These skills transfer to daily life, creating resilience that does not depend on having resolved every traumatic memory. Similarly, neurofeedback that enhances alpha waves or reduces high-beta arousal builds the nervous system’s flexibility, its capacity to shift between states as context requires.

Van der Kolk’s emphasis on theater and movement therapies extends this principle further. When trauma survivors participate in improvisational theater or group movement work, they practice coordinating action with others, reading social cues, expressing emotions safely, inhabiting their bodies with confidence rather than shame. These experiences directly counter the isolation, hypervigilance, and bodily disconnection that trauma creates. The healing occurs not through insight but through repeated embodied experiences of safety in connection, what Stephen Porges’s polyvagal theory calls social engagement.

Polyvagal theory complements van der Kolk’s work by mapping how the vagus nerve mediates the nervous system states that he describes. Porges distinguishes between ventral vagal activation associated with safety and social engagement, sympathetic activation associated with fight or flight, and dorsal vagal activation associated with shutdown and dissociation. Trauma pushes people into chronic sympathetic or dorsal states, and healing requires helping the nervous system find its way back to ventral vagal functioning. Techniques that stimulate the ventral vagus, whether through singing, humming, slow breathing, or safe social connection, directly address the physiological dysregulation that maintains trauma symptoms.

For therapists integrating depth psychology with neuroscience, van der Kolk’s work suggests that archetypal material and trauma responses may be inseparable. Jung’s archetypes of the wounded child, the persecutor, the rescuer, these are not merely symbolic but reflect actual nervous system states and relational patterns that trauma creates. When a client encounters the wounded child in dreamwork or active imagination, they are accessing neural networks shaped by early attachment trauma, complete with the bodily states of helplessness and fear. Working with this archetypal material requires holding space for the somatic activation that arises, helping the nervous system learn that feeling these states need not overwhelm.

The shadow in particular becomes comprehensible through van der Kolk’s lens. What Jung called the shadow involves not just disowned psychological qualities but all the parts of experience that required dissociation for survival. For someone who experienced childhood abuse, the shadow may contain not only anger at perpetrators but also attachment to them, not only terror but also bodily arousal, not only helplessness but also aggressive protective impulses that were forbidden. Integrating shadow requires tolerating the full range of bodily states associated with traumatic experience, allowing what was split off to return to consciousness without retraumatization.

For individuals doing their own psychological work, van der Kolk’s research offers guidance about what healing requires. Talk therapy alone rarely resolves trauma because trauma bypasses language centers and encodes subcortically. Someone can understand intellectually that they are safe now while their body remains locked in defensive patterns learned decades earlier. Healing requires engaging the body directly through practices that build interoceptive awareness, increase vagal tone, and create experiences of safety in connection.

Practices like yoga, martial arts, dance, or even walking in nature can provide this embodied healing. The key is learning to notice bodily sensations without either dissociating from them or becoming overwhelmed, what therapists call building window of tolerance. Someone who dissociates during difficult emotions needs to practice staying present to subtle sensations, perhaps noticing the temperature of their hands or the pressure of their feet against the floor. Someone who floods with panic needs to practice pendulation, moving attention back and forth between activation and calm, learning that arousal rises and falls rather than escalating indefinitely.

Relationships offer another crucial arena for healing. Van der Kolk emphasizes that feeling safe with other people is probably the single most important aspect of mental health, that safe connections are fundamental to meaningful lives. This aligns with attachment research showing that secure relationships provide the regulatory support that traumatized nervous systems need. When someone feels seen and accepted by another person despite their vulnerabilities, when they can express difficult emotions without being abandoned or overwhelmed, their nervous system learns that connection is possible, that the world need not remain perpetually threatening.

The challenge is that trauma often damages the very capacity for connection that healing requires. Someone who learned that caregivers were sources of threat as well as comfort may find intimacy triggering, may push away the very support they need, may dissociate when relationships become too close. Healing these relational patterns requires patience, titration, and often professional support, because the activation that arises in close relationships can exceed what someone can regulate alone.

Van der Kolk’s advocacy for MDMA-assisted therapy reflects his recognition that some trauma is too intense to approach through gradual exposure alone. MDMA appears to temporarily reduce amygdala reactivity while enhancing activity in prefrontal and social engagement systems, creating a neurobiological state that allows people to access traumatic material with less defensive activation. Under these conditions, memories that usually trigger overwhelming panic can be processed with compassion and connection. The therapy provides not simply exposure to feared memories but a fundamentally different emotional context for relating to those memories.

The research on psychedelics connects to depth psychology’s interest in non-ordinary states of consciousness. Jung’s explorations of the collective unconscious often involved spontaneous visionary experiences that shared features with psychedelic states, including dissolution of ego boundaries, encounter with archetypal images, and feelings of cosmic connection. He recognized that such states could provide healing experiences that ordinary consciousness cannot access, though he also warned about the dangers of inflation and psychotic decompensation. The careful therapeutic containers being developed for psychedelic-assisted therapy address these concerns, providing integration support to help people metabolize insights that arise during non-ordinary states.

Van der Kolk’s career has not been without significant controversy beyond the memory wars. In 2017, he was removed from his position at Harvard Medical School reportedly due to allegations of mistreating colleagues at the Trauma Center. Multiple employees described an environment of fear and intimidation, with van der Kolk allegedly responding to dissent with anger and retaliation. He disputes these characterizations, claiming the real reason involved the university’s fear of lawsuits related to his recovered memory testimony. The Trauma Center, which he founded and directed, separated from the Justice Resource Institute in 2018, with van der Kolk establishing the Trauma Research Foundation as an independent organization.

These workplace allegations complicate van der Kolk’s legacy. Someone who has spent decades advocating for trauma survivors and developing humane treatments has been accused of creating a traumatizing work environment for his own staff. This paradox reflects a pattern sometimes seen in helping professions, where individuals drawn to trauma work may be working out their own unresolved material, where the very intensity that fuels groundbreaking work can manifest as interpersonal difficulties. It serves as a reminder that understanding trauma intellectually does not guarantee emotional regulation or relational skill, that healing is a lifelong process rather than a destination reached.

Van der Kolk’s influence on contemporary trauma treatment is undeniable despite these controversies. His integration of neuroscience with body-based therapies has shifted mainstream psychiatry’s understanding of PTSD from a disorder of memory and cognition to a disorder of physiology and regulation. His advocacy for approaches that directly address the nervous system, whether through EMDR, yoga, neurofeedback, or psychedelics, has legitimized modalities that were once dismissed as alternative or fringe. His emphasis on developmental trauma has forced recognition that childhood maltreatment creates its own syndrome distinct from adult-onset PTSD.

For the field of depth psychology, van der Kolk provides empirical grounding for insights that Jung articulated phenomenologically. The body as unconscious, the role of somatic symptoms in psychological disturbance, the need for embodied rather than merely intellectual integration, these Jungian themes find validation in contemporary neuroscience through van der Kolk’s research. His work demonstrates that the wisdom of depth psychology and the precision of neuroscience can inform each other productively, that honoring subjective experience and conducting rigorous research are not contradictory but complementary.

The next generation of trauma therapists will likely synthesize cognitive, somatic, and depth psychological approaches more seamlessly than previous generations could. Training programs increasingly teach polyvagal theory alongside psychodynamic concepts, neurofeedback alongside dream interpretation, somatic tracking alongside analysis of transference. This integration reflects van der Kolk’s vision that effective trauma treatment requires multiple entry points, that some healing happens through processing specific memories, some through building physiological regulation, some through meaning-making and narrative reconstruction.

What van der Kolk has given psychology is permission to take the body as seriously as the mind, to recognize that feelings and thoughts emerge from physiological substrates, to work directly with nervous system states rather than assuming verbal insight produces change. He has shown that trauma is not simply something people think about but something they live through their bodies, and that healing requires the body to learn that safety is possible. In doing so, he has helped bridge the divide between medical psychiatry and depth psychology, between neuroscience and phenomenology, between what we can measure and what we can only witness.

Influences and Legacy

Van der Kolk’s work builds on multiple theoretical traditions. Abram Kardiner, the psychoanalyst who treated shell-shocked World War I veterans, first described traumatic stress as a physioneurosis in 1941, recognizing that trauma creates lasting physiological changes. Van der Kolk recovered this insight, demonstrating through modern neuroscience the specific ways trauma recalibrates the nervous system. Pierre Janet, the 19th-century French psychiatrist and psychologist, proposed that trauma causes dissociation, a splitting of consciousness that prevents integration of overwhelming experience. Van der Kolk extended Janet’s phenomenological observations with neuroscientific evidence about how traumatic memories are encoded and retrieved.

Judith Lewis Herman, author of Trauma and Recovery, shaped van der Kolk’s understanding of complex trauma and the importance of safety, remembrance, and reconnection in healing. Herman’s distinction between simple and complex PTSD influenced van der Kolk’s work on developmental trauma disorder. John Bowlby’s attachment theory provided the framework for understanding how disrupted caregiving creates lasting vulnerability to stress and difficulty forming secure relationships.

Francine Shapiro, who discovered EMDR, influenced van der Kolk’s approach to memory reprocessing. His research helped legitimize EMDR within mainstream psychiatry by providing neuroimaging evidence for its mechanisms. Peter Levine, creator of Somatic Experiencing, shaped van der Kolk’s emphasis on completing interrupted defensive responses and working with autonomic discharge. Stephen Porges, developer of polyvagal theory, provided the neuroanatomical framework for understanding how trauma affects social engagement systems.

Van der Kolk has influenced countless clinicians and researchers working in trauma treatment. Pat Ogden developed Sensorimotor Psychotherapy drawing explicitly on his insights about subcortical processing. David Grand, creator of brainspotting, builds on van der Kolk’s work on eye position and trauma processing. Janina Fisher integrated his neuroscience findings with structural dissociation theory to create trauma-informed approaches for working with parts.

His advocacy for body-based therapies has transformed trauma treatment training programs. Organizations like the National Institute for the Clinical Application of Behavioral Medicine promote his integrative approach through continuing education. Internal Family Systems therapy, developed by Richard Schwartz, has gained wider acceptance partly through van der Kolk’s neurobiological explanations of how parts develop and function.

The research on neurofeedback inspired clinicians like Sebern Fisher to develop specialized protocols for developmental trauma. His work on yoga influenced the development of trauma-sensitive yoga programs that are now taught internationally. The MDMA research he led has accelerated the psychedelic therapy movement, with multiple organizations now developing training programs for MDMA-assisted therapy in anticipation of FDA approval.

Van der Kolk’s impact extends beyond clinical practice into social policy. His testimony before Congress about childhood trauma influenced funding for the National Child Traumatic Stress Network. His emphasis on how early adversity creates lasting physiological changes has informed the Adverse Childhood Experiences research showing dose-response relationships between childhood trauma and adult health outcomes.

For depth psychology, van der Kolk provides the neuroscientific grounding that makes Jungian concepts more accessible to empirically oriented clinicians. His demonstration that trauma lives in the body validates Jung’s emphasis on the psychoid nature of psychological material. His research on how therapeutic approaches work suggests that Jungian techniques like active imagination and sandplay succeed not through cognitive insight but through accessing subcortical processing systems. The synthesis of depth psychology’s attention to meaning with neuroscience’s understanding of mechanism represents van der Kolk’s enduring contribution.
